A Non-Fungible Token (NFT) is a unit of data stored on a digital ledger, called a blockchain, that certifies a digital asset to be unique and therefore not interchangeable.NFTs can be used to represent items such as photos, videos, audio, and other types of digital files. Access to any copy of the original file, however, is not restricted to the buyer of the NFT. While copies of these digital items are available for anyone to obtain, NFTs are tracked on blockchains to provide the owner with a proof of ownership that is separate from copyright.
The NFT market value tripled in 2020, reaching more than $250 million. During the first quarter of 2021, NFT sales exceeded $2 billion
Considering the booming of NFT since 2020， $2M USD for this domain is relatively cheap.
